3 Dehumidification mode
The unit have dehumidification control by a reheat coil, which is under the evaporator coil. To execute
dehumidification, controller setting is required. (Refer to Page 3-12)
In dehumidification, the Reheat Solenoid Valve (RSV) opens to flow high pressure and high temperature
refrigerant to reheat coil. The "DEHUMID" LED lamp will light up.
The following setting can be made:
1) Dehumidification range: 60–95%RH

Body : EDM-B804DM-1
This unit adopts an electronic expansion valve.
The electronic expansion valve controls the
optimum refrigerant flow rate automatically,
using the temperature sensor at the evaporator
inlet and outlet pipes.
In case of emergency including controller
malfunctions, refer to the chapter of
troubleshooting, section 6.5, Emergency
operation.
(1) Replacing the coil
q Loosen the lock nut, then remove the coil

installation is 6.9 to 16.7 N m (70 to 170kgf
cm).
eRestore the binding bands and the lead wire
into the original state.
rAfter replacing, carry out refrigerant leakage
check, and make sure that there are no leaks.
